    The technical expertise needed to build the world's first commercial quantum computer is immense, which is why D-Wave Systems Inc. turned to Omni Circuit Boards to help them take up the challenge.

    The collaboration began in April of 2005, with Omni providing cutting-edge prototype circuit boards incorporated in the initial set of D-Wave quantum trials.

    As D-Wave's needs have grown throughout the process, Omni has increased design and production capabilities every step of the way to meet them.


    The Challenge
    Our challenge was multifaceted, and began with the need to determine the materials and processes required to manufacture printed circuit boards that could meet a number of needs, including:

    • The ability to operate in a cryogenic vacuum
    • The strength to withstand the rigors of reliable cycling between room temperature and temperatures colder than those found in deep space, over four orders of magnitude in temperature change
    • The versatility to enable multi-component superconductive interconnects
    • The ability to meet D-Wave's aggressive space and trace width requirements
    • The need for construction with materials that would support superconductivity


    The Result
    Through an intense collaborative effort, spurred by innovative thinking and technological advances, our team has produced a fine line immersion white tin finish printed circuit board. The process for manufacturing each specific board depends on the necessary part and application, but typically requires edge plating, mask over white tin, and a selective gold and white tin finish.

    The Next Step
    As the project moves forward, further research and development efforts will be required to support the next generation of D-Wave superconductive ICs. While this effort continues to test Omni's technical capabilities in CAM, machining, and chemical processes, it also adds to our ever-growing base of technical expertise and client-focused abilities.
